Claims.

This invention relates generally .to girdlesor sleeves for paint brushes, the bristles whereof, it is requisite to vary effectively in length accord-A ing to the Width of surface to beA covered.

More specifically the present improvements have reference to what' may be conveniently termed a quick acting reciprocatable sleeve for paint brushes of which thefbristlepack is,V preferably preformed oval or its equivalent in shape.

1. The primary object -ofthis invention to avoid bending or damage to the 'bristles of the brush when installing the sleeve, and Athisis accomplished by so constructing the sleeve and the brushthat the former may be placed in its workingvposition, initially or after having been removed for cleaning by slipping itover the handle of the brush as .a .one piece unit.

2 Anetherbieet iste. provide agirdleof-nevel Construction wherebvrant Collecting ent-he. .inside-thereof ,is l prevented from .workingbaek to the paint brush handle.

3. A further `object is to provide tliegirdlefwith a handle .or grip Y,to failitateits ins; ntmevement back or forthoyer the will ofthe user.

-4- A still .further ebieetis y.to provide .mean-s for preventing .paint `riuiiiug ugento .the outside of the girdle as itis pushed down .over the bristle pack and Yultimately reachinsthe .grip fof-the sleeve.

5.. Another object of this inventionisto :automaticallv held the sleeve .in any desiredfpesition Vwithinits .limit of travel.

v.6. A -furtherebject is to ',providea `temporary reserveir. for excess paint .en ther-exterior@ the bristle paektifdesiredf7. A stillzfurtherpbject is .toavoid paint dripping from the bristle ,pack .when the .sleeve .is pushed over them.

.8. An. additional ,object of .'.inventien Yis .t9 have the `sleeve completely free iof openings whereby paint Works throughthem with-the consequentannoyances.

.9..Anether .Qbieetof :this invention is :to .be ablefto quickly and.easily retrievey the sleeve or girdle from .the brush .iorpurposes of cleaning.

,The combination of fthe above .fimrreuements provideY a most practical working brushJ .especially for. those persons Vless experienced in painting. The, reciprecatable Asleieveis .so A:formed thatgit purposely avoids compressing .the bristles.. lhis is most desirable for the bristlesfif compressed :at .the .line :fof emergence from 4the girdle are amable to absorb .paint .to the :full extent above thisfline. when vdipped for a :new supply. For `my. purpose this is highly objectionable, for when painting the putty .strip :offa window frame, :it requires. a very .short brist1eexposure; ifsmearing the glass is to be avoided. would require a frequency of dipping, which is not lonly annoying but also slows down the speed of coverage.

Furthermore myinvention allows the user to instantly uncoverthe full length of bristles pro- V4trudingfrom the brush ferrule or 4band in which the bristles are fastened without the necessity of removing thegirdle from the brush.

Like characters of reference are applied to corf responding parts in all several views.

In the embodiment of my invention as show by Figs. I to XII inclusive, the numeral I desig' nates the bristle pack, preferably oval in s'liap'e,v

and 2 the combination ferrule and guidepiece,

while 3 is the conventionally' rounded taperedv handle but having an oval shaped shank 4, the three pieces joined together to form the oval sash brush 5. The ferrule 2 -is oval in section throughout its length, rather than oval at its bristle end only and tapered to roundV at the handle end to receive a round handle as ordinarily constructed. This oval cross section throughout its length, allows the oval shaped quick acting, reciprocatable sleeve 6 with its handle 1 to fit snugly and to slide completely over it as a guide piece. This same oval cross section is maintained in the shank 4 and functions in part as an extenf sion to the ferrule 2 vand while this is desirable it is not essential except for that portion actually entering the ferrule 2. Should the shank 4 be made round, then its greatest diameter must at no point be greater than thesmallest diameter of the sleeve 6 in order that the latter may be passed over it. The ferrule 2 is preferably made of metal while the shank 4 with the handle 3 is made of wood or moulded from a plastic material.

In the particular form of my invention as shown in Figures I and II the removable stop pin`8 is provided. This pin 3 is so positioned in the shank 4 that the back travel of the sleeve 6 is stopped just after the bristle pack I is completely uncovered. For purposes of cleaning, the pin 8 is quickly removed, the sleeve 6 withdrawn over the handle 3, and whenassembling'the sleeve 6 is slipped over the handle 3 ontov the shank 4 and guide piece 2 and the stop pin 8 positioned inthe shank 4 avoiding the possibility of the least damage to the bristle pack. y

In the modication of my invention as shown in Figures III and IV, I have incorporated in the shank 4 in close proximity to the ferrule 2, the wiper 9 made of a yieldable material, such as felt or a synthetic rubber which is not affected by oils commonly found in paint as is rubber made of latex. My brush when used for the purpose intended requires frequent change of position of the sleeve 2. Paint, under this action, even though the sleeve 6 fits snugly on the guide piece 2, soon works its way back to the shank 4 and handle 3 with its resultant annoyances. The wiper 9, which is tted snugly in the rectangular groove II] encircling the shank 4, has a slightly greater perimeter than that inside the sleeve 6. This puts the wiper 9 in compression when in place within the sleeve 6. It is obvious that this arrangement effectivelystops the spread of the paint to the handle. The compressed wiper 9 also acts as a brake when the reciprocatable sleeve 6 is moved from one position to another, holding the sleeve 6 in the desired place.`

Another modification shown in Figs. IV is the spring stop II permanently fastened to the handle 3 by its brad-like end I2, the stop I3 forms a part of the spring arm I I and enters the registering hole I4, drilled through the handle 3, when the spring arm I I is pressed down allowing the removal of the reciprocatable sleeve 6.

Referring now to the form of my invention as shown in Figs. V and VI, the modification consists in attaching the wiper to the reciprocatable sleeve rather than fastening to the handle shank. The preferred location is within the recess of the sleeve grip 'I. This grip 1 is shaped into a rectangular rib. Into this combination grip and wiper holder 'I is fastened the preferable prey-formed oval shaped wiper I5. The oval hole cut in this wiper I5 is of a slightly smaller perimeter than the perimeter of the oval shank 4. It is III and obvious that when the sleeve is threaded over the handle 3 onto the shank 4 and guide piece 2, the wiper I5 will be slightly compressed around the shank 4 and will forrn an effective seal against the paint spreading to the handle 3. In this constructionthe wiper I5 moves with the sleeve 6 insteadA of remaining stationary. Y v

In the above embodiment also is shown another type of spring stop, attached to and moving with the sliding sleeve 6 thereby removing all projecting parts from the handle and its shank 4. As shown a spring I6 is fastened to the reciprocable sleeve 6 at the point II. lThis spring I6 is shaped to be passed through the hole I8 of the sleeve 6 in close proximity to the sleeve grip 1, its free end or shoe I9 is bent so as to approximately parallel the spring arm I6 and just clears the Wiper I5. The shank 4 is grooved to just receive the shoe I9 With the deeper recess at the ends thereof to form the vertical shoulders 20 and'2l. It is obvious that these shoulders 20 and 2| limit the travel of the sleeve 6 by acting as stops to the shoe I9. The spring set is such as to always exert a downward pressure on the groove 22. When the sleeve'6'is moved over the bristle pack I to expose but a very small amount of the bristle pack itis stopped by the shoe I9 contacting the shoulder 20 and when the sleeve 6 is moved in the reverse direc# tion the sleeve I9 contacts the shoulder 2I just as the bristle pack is completely uncovered.

While the principal objective 'of the spring arm- I6 functions to limit theV travel of the reciprocatable sleeve 6, its downward pressure -on' Yits groove 22 assists in holding the sleeve 6 in -any set position. The face 23 ofthe ovalshank] is so proportioned as to give a suiicient opening for the shoe I9 toclear the shoulder 22 when the spring arm I6 is raised tothe inner wall of the sleeve 6. This allows the quick ywithdrawal of the sleeve 6 from the shank 4 and'oiithe handle 3 for cleaning purposes. When replacing the reciprocatable sleeve 6 thevshoe 'I9 will automatically ride up thev handle 3, then across the face 23, and snap down in place in the groove 22 as it clears the shoulder 2I. .A l

In the form of my inventionas shown' in Fig. VII the modification consists in forming -aare or guard 24 at that end of the Ysleev`e`-6 'which moves over the bristle pack I. `This`guardn24 serves to prevent any excess paint on the exterior of the bristle packl, from riding up fand over onto the lexterior side of Athe sleeve "G'asA it 'is pushed down over the bristlepack. and` later spreading along the'sleeve 6to' thefgrip 'I with its consequent annoyanc'cs.

Referring now to the form of'myin'vention'as shown in Fig. VIII, the modification consists in including with the reciprocatable sleeve 6 what I choose to call paint storage pockets. I find that when Vthe sleeve isof an open construction; the motion of the bristles, as the user movesithe brush Vback and forth over the work, causes any.

excess paint to press through the openings with its obvious annoyances. I have taken advantage of this effect and nd by forming in the reciprocatable sleeve 6, a pocket in the form of one or more annular outwardly extended corrugations or ribs 25 or their equivalent, that these pockets 25 illl With paint when the bristle pack is holding an excess thereof, and empty again as the paint is used up on the work. This assists in preventing brush drip, gives the brush greater paint holding capacity, especially when the sleeve 6 is positioned for a short bristle eX- posure as is required for example when the brush is used for painting the putty strip of a window frame.

I also find that when the user of my combination brush and quick acting reciprocatable sleeve has`but one hand available to make the desired adjustment, that the sleeve 6 may be more easily withdrawn from the bristle pack I by pressing the handle end against his body. If wearing light clothing the pointed end of the standard handle tends to penetrate through the clothing. I have therefore modied my invention by shaping the end of the handle 3 with a blunt cap 25 as showny the diameter of which is less than the smallest diameter of the reciprocatable sleeve 6, which allows the reciprocatable sleeve 6 to pass over it when removing or replacing it on the brush.

In the embodiment of my invention as given in Figs. IX and X, I have shown a combination of elements, which embody desirable features described and illustrated previously, in which the oval sash tool or brush 5 formed of the bristle pack I, fastened in the unique combination ferrule and guide piece 2, the handle 3 with its oval shank 4 having formed therein the recess 22 with its vertical shoulders 20 and 2i with the face 23 so proportioned that ample clearance is given to the shoe I9 of the spring stop I6, for the quick acting reciprocatable sleeve E tting snugly on and around its guide piece 2 to be withdrawn over the handle 3. The spring stop arm I6 soldered to thge metal sleeve 6 passes through the hole I8 of the sleeve 6 and forms the shoe I9 to engage one of the vertical shoulders 20 or 2l and stop further travel of the reciproca-ble sleeve B. Formed in the shank li is the circumscribed rectangular groove I around which is snugly fitted and fastened the felt wiper 9 of suilcient thickness to press slightly against the oval shaped sleeve 6. The end of the sleeve Ii covering the bristle pack I is flared to form the guard 24 while the end thereof nearest the brush handle 3 is expanded to form a handle or grip 1 used to move the sleeve backward or forward.

In the embodiment of my invention shown in Figs. XI and IUI, I have used the combination of elements described and illustrated previously but have replaced the stationary wiper circumscribing the handle shank with the wiper I fitted and held in the sleeve grip 1. The paint pockets 25 are modied in shape from those shown in Fig. 8 to form vertical shoulders 21 in place of the rounded corrugations. The flat or button end 26 of the brush handle 3, illustrated and described in connection with Fig. VIII is also embodied in this combination.

While the foregoing descriptions have made f reference to an oval sash tool, a paint brush with the bristle pack oval in section, it will be without departing from the essential features of said invention as defined by the following claims.

Having thus described my invention, I claim:

l. The combination with a paint brush having bristles, a handle, and a ferrule for holdingthe bristles, of a sliding girdle mounted to embrace and contact with the bristles, and a Wiper tc prevent the spread of paint to the handle by the sliding girdle.

2. The combination with a paint brush having bristles, a handle, and a ferrule preferably made of metal, of a sliding girdle, a spring arm fastened thereto and pressing against a recess provided in the brush handle, and shoulders formed at the ends of the recess to limit the distance of travel of the sliding girdle.

3. The combination with a paint brush having bristles, a ferrule for holding the bristles, having the same diametric dimensions throughout its length, and a handle, having a shank of the same diametric dimensions throughout its length and recessed to form shoulders at the ends thereof, of a sliding girdle, having a hand grip at one end, and a flaring guard at the opposite end, a spring attached to the girdle, one end being free and pressing against the recess in the handle shank, and limiting the travel of the sliding girdle by engaging either one or the other of the shoulders formed by the recess, a wiper, preferable of felt, fixed to and positioned around the handle shank in proximity to the ferrule.

4. In a paint brush the combination of a bristle pack, a conventional paint brush handle having at one end a shank portion from the end of which the bristle pack projects, said shank portion being of substantially uniform cross section throughout its length and exceeding in cross sectional area the area of the cross section of all parts of the other end portion of the handle and the normal cross sectional area of the bristle pack, and a one piece inelastic girdle of uniform bore conforming in cross section to the cross section of the shank and separable therefrom and slidably mounted thereon for endwise movement, whereby the girdle can be applied to the shank from the end of the handle opposite the bristle pack and can be positioned to cover a portion of the bristle pack Without compressing it, the portion of the wall of the girdle positionable over the bristles being imperforate.

5. The combination with a pain brush having bristles, a bristle holding ferrule of substantially the same cross sectional area throughout its length and an elongated tapered handle portion having a shank, of a sliding girdle detachable from the rest of the structure and which may be placed in position on the ferrule by sliding it over the end of the shank onto the ferrule, the portion of the wall of the girdle positionable over the bristles being imperforate.
